BCR405U
概要
Linear LED driver IC for low power LEDs
The BCR405U linear LED driver IC is tailored to drive low power LEDs in general and automotive lighting applications.
特長
- LED drive current preset to 50mA
- Output current adjustable by resistor up to 65mA
- Supply voltage up to 40V
- High side current control, PNP transistor power stage
- PWM dimmable by external transistor
- Up to 750mW power dissipation in a small SC74 package
- Negative thermal coefficient reduces output current at higher temperatures
- Automotive qualified according to AEC Q101
利点
- Driving current always under control for homogenous light output
- Longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient)
- Easy paralleling of drivers to increase current
- Contributes to longevity and reliability of LED system
推奨アプリケーション例
- LED strips, signage and channel letters
- Commercial, architectural and residential lighting
- Shop, ship, train and aircraft lighting
- Automotive interior lighting
